Background and study aims
As fluids tend to be easier to consume compared to solid food in women with nausea and vomiting of pregnancy (NVP), this study aims to evaluate the response to most common fluids tolerable to women experiencing NVP that are least likely to evoke nausea or vomiting, to obtain a scientific basis to construct dietary advice for women with NVP or hyperemesis gravidarum (HG).

Who can participate?
Pregnant women aged 18 years and above with hyperemesis gravidarum

What does the study involve?
A two-part study is proposed with an initial questionnaire comprising 13 common local beverages, with a view to selecting four of those beverages for a fluid tasting trial. Participants are required to drink four types of fluids in a random order. These fluids include water, ginger-flavoured drink, orange juice and lemon drink (water and ginger-flavored drink are compulsory, whereas orange juice and lemon drink are the two top ranking fluids based on the first part questionnaire). Fluid tasting involves swallowing 30 ml of a liquid. In the presence of the investigator, participants are required to take each drink, hold it for 3 seconds and rinse it in the mouth, then slowly swallow. This is repeated for the four fluid items in a randomly allocated order and participants are observed for 10 minutes after each fluid. Participants rinse their mouth with plain water at the end of tasting each fluid before proceeding to the next fluid. Drinking plain water at any time during the tasting is allowed as well. Participants are asked to score the severity of their nausea as a score from 0-10 before tasting (0 minutes), and 2 and 10 minutes after drinking each fluid. Participants are also monitored for their response after tasting, whether they have any urge to vomit, heave or gag in the 10 minutes after each fluid item is ingested. Participants provide an agreeability score on each fluid tasted at the end of 10 minutes on a scale from 0-10. 15. If participants are unable to tolerate the fluid or vomit during the test, they are allowed to rest first and continue the tasting later.

What are the possible benefits and risks of participating?
This study will outline a dietary/fluid intake recommendation for women experiencing nausea and vomiting in pregnancy as fluid intake is necessary during this period. It brings awareness of the different fluids that are deemed more tolerable yet readily available to ingest. There are no risk factors.

Where is the study run from?
1. University Malaya Medical Centre (Malaysia)
2. Hospital Selayang (Malaysia)
3. Hospital Putrajaya (Malaysia)

When is the study starting and how long is it expected to run for?
October 2019 to March 2021 (updated 05/01/2021, previously: January 2020)

Who is funding the study?
University Malaya Medical Centre (Malaysia)

Scientific titleFluid tasting trial in women admitted for hyperemesis gravidarum
Study acronymFLUTAH
Study objectivesCertain fluids are better tolerated in women with hyperemesis gravidarum (HG). The researchers expect that fluids identified as potentially best tolerated from the questionnaire will be supported by the experimental data thus providing a scientific basis to construct fluid advice in HG.
Ethics approval(s)Approved 29/04/2019, Medical Research Ethics Committee, University of Malaya Medical Centre (Medical Research Ethics Committee of University Malaya Medical Centre. Lembah Pantai, 59100 Kuala Lumpur, Malaysia; Tel: +60 (0)3 79493209; Email: umrec@um.edu.my)
Health condition(s) or problem(s) studiedHyperemesis gravidarum
InterventionParticipants will be required to drink 4 types of fluids in random order. These fluids include water, ginger-flavoured drink, orange juice and lemon drink (water and ginger-flavored drink are compulsory, whereas orange juice and lemon drink are the 2 top ranking fluids based on the first part questionnaire).
1. Patient admitted to Gynecology ward UMMC with presumed diagnosis of hyperemesis gravidarum.
2. Screening of patient is done with the Eligibility Form (EF) and patients who fulfill the inclusion and exclusion criteria are approached for recruitment.
3. Patient will be provided with a Patient Information Sheet (PIS) and a verbal explanation of the study.
4. If the patient does not agree, they will be excluded from the recruitment and subsequent care will be according to standard treatment protocols.
5. Patients who agree to participate in the study will personally sign and date the Consent Form.
6. The participant will be interviewed by the investigator and Case Report Form (CRF) is filled up by the investigator.
7. Fluid tasting requires the swallowing of a liquid measured accurately with a syringe of 30 ml per serving in a standard 50ml disposable cup.
8. In the presence of the investigator, participants are required to take each drink, hold it for 3 seconds and rinse it in the mouth, then slowly swallow. This is repeated for the 4 fluid items in a randomly allocated order and observed for 10 minutes after each fluid item.
9. Participants will be required to rinse their mouth with plain water at the end of tasting each fluid item before proceeding to the next fluid item. Drinking plain water at any time during the tasting is allowed as well.
10. Participants will be asked to score the severity of their nausea in a visual numerical rating score from 0-10. This scoring will be done before tasting (0 minutes), 2 and 10 minutes after ingestion of each fluid item, timed using a stopwatch
11. Participants will also be monitored for their response after tasting, whether they have any urge to vomit, heave or gag in the 10 minutes after each fluid item is ingested.
12. Participants will be asked to provide an agreeability score on each fluid item tasted at the end of 10 minutes in a visual numerical rating score from 0-10.
13. Participants will be given an Outcome Form (OF) to answer after ingestion of each fluid item. Below are the items that participants are required to record in that form:
• Nausea score in Visual Numerical Rating Scale (NVNRS) at 0, 2 and 10 minutes
• Signs questions (S_Q) to each participant after tasting each fluid item at 10 minutes
• Agreeability score in Visual Numerical Rating Scale (AVNRS) at 10 minutes
14. Participants will be given a gap of 2 minutes in between tasting of each fluid item to fill up the Outcome Form and rinse their mouth
15. If participants are unable to tolerate the fluid item or vomit during the test, they will be allowed to rest first and continue the tasting later.
16. Data collection by the investigator will be completed when:
• Questionnaire Forms are completed by participants
• Case Report Forms are completed when participants are discharged
Intervention typeOther
Primary outcome measure1. Participant’s nausea score measured using a visual numerical rating scale from 0 to 10 before tasting (0 minutes), 2 and 10 minutes after tasting each fluid item
2. 'Agreeability score’ on each fluid item measured using a visual numerical rating scale from 0 to 10 at 10 minutes
3. Signs questions (S_Q) to each participant after tasting each fluid item at 10 minutes
Secondary outcome measuresObservations of each participant after tasting each fluid item, i.e. whether they have any urge to vomit, heave or gag in 10 minutes after each fluid item is ingested
